I'm sorry, Pete, but I don't see anything there that a serious machinist or serious amateur machinist would think was reasonable. With the standard 'tee-handle' chuck wrench on the (Yes, an Atlas) chuck, if you use the 'Portnoy's Complaint Method' (three fingers spinning the wrench), you can move it just as fast as any of those except the dumb idea of driving it with a power drill! I mean, why? The only time you really need FAST chucking and de-chucking is when you're doing production cut-off work. Then you need a QA chuck, not a scroll chuck! Lloyd And using a drill on a 4 jaw as well. Maybe the 4 jaw is a hobby grade version - and acts as a 3. 4 jaws should have all 4 independent allowing offsetting and very good centering. I have a Sheldon 11-44 with 3 and 4 jaw chucks. A wood lathe with 3, 4 and another special 4 jaw. Martin |

Pete Stanaitis -------------- The question arises, how much does one adjust chuck jaws? I don't believe it is a significant portion of the machining time. and for a four jawed chuck, as the guy shows using a power drive, my experience has been that the majority of the time was spent getting rid of the last few thousands of runout. -- Cheers, John B. |

: and for a four jawed chuck, as the guy shows using a power drive, One gets the impression that the particular machinist in that article had nothing worthwhile to offer the community, so he documented an abusive technique he never really thought out. He probably _doesn't_ "get rid of the last few thousandths of runout", so it never occurred to him that his is a bad way to 'adjust' a 4-jaw chuck (or any chuck, for that matter). I seldom do rapid repeated cutoff work, but I was gifted a nice 3" precision 6-jaw Quick-acting chuck, so when I do such work, it's both fast and pretty accurate. Kind of a funny story, that. I built a precision crimper for 5/32" o.d. brass tubing for a client for fixing electric igniters into short lengths of that tubing. He was using the assemblies as movie stage 'ammunition' for prop guns in a country where real firearms are prohibited even as movie props. The chuck became the 'crimper' part, as it would very precisely neck the tubing down with a pretty six-point 'star crimp'. We didn't even have to modify it.. just mounted it in a hollow-framed stand, and clamped a pull handle to the closing ring. The idea fell through with the movie studios. He later dropped off the beautiful chuck-in-stand with "You want this boat-anchor?" "Well... sure, thanks. I might find SOME use for it." G Lloyd |

Yeah, I guess everyone wants to portray journalists who collect information for reporting in trade manuals like this and others as somehow either too detached, crazy, ignorant, corrupt or biased or even worse. But notice how difficult it would be to be crazy AND corrupt AND biased AND all of that that everyone says and even worse than all that all at the same time? That's how you know that the journalist is neither one of them. So you should believe the report. |

Well, guys, I feel thoroughly beat up now. But I really don't understand all the vitriolic comments.
Maybe I failed to explain WHY I offered these ideas: The main reason for even considering the speed handle and drill ideas is when reversing chuck jaws or when going from a really small chuck opening to a really large chuck opening, particularly with the 4 jaw chuck. Just go out to your shop and time yourself for reversing the jaws on a 8" 4 jaw chuck using the tee handle, then try it with the speed handle. I have been "spinning the tee handle" for a long time and I am here to tell you that you shouldn't knock the speed handle until you try it. The drill and speed handle thoughts were never meant to deal with making fine adjustments. But the two little sockets/square stock tools are up to the job. I probably wouldn't use the drill method myself, but I added it simply because I had seen it somewhere. Pete Stanaitis -------------- |

What's causing such a deluge of off-topic stuff, though? Like politics. Politics has always swamped most non-related newsgroups as long as email has been around. Maybe its because newsgroup participants hate most of what they see and hear in society to such a great extent that they simply can't hold back. But what is the underlying cause?

"What do you know about Roman blacksmithing? " Not a lot. Except that they sure did a lot of it. I do know that they were producing wrought iron all over the parts of the world that they had conquered. I suppose that ran right up to about 450AD. Producing wrought iron is a lot of work. We make a couple of runs at it each year around here. The reason I say this, is that they wouldn't have gone to all that trouble if they weren't going to make a lot of stuff out of it. The trouble for archeologists is that the iron items don't often survive because of rust. Can you be more specific with your question? I know several guys who can supply lot more detail. I do a fair amount of "traditional" blacksmithing. That means, to me, that I mostly make stuff that people would have used around 1870 and before. Many of those items wouldn't have changed a lot from what a Roman blacksmith would have been asked to produce. When making wrought iron the way they did it, they often got chunks of higher carbon steel here and there in the bloom. Sometimes (all too often) the whole bloom would be of a higher carbon content than needed. These pieces would be saved for edging tools that needed it. We did a couple of 10 day 24X7 smelts back in about 1992 and 1995 or so where we did our best to replicate smelters of the 150 BC period, attempting to produce wrought iron FOR the blacksmiths of that period. We learned a lot and got very dirty sifting 8 tons of charcoal for the furnace. I'll bet the Romans did too. OT??? Pete Stanaitis --------------- |

Pete Stanaitis --------------- Several years ago I watched a show about the unearthing of metal Roman artifacts in England. They had many examples of weapons that had bronze handles and iron alloy blades. An "excellent" sample was shown and almost all of the iron had rusted away, just a thin delicate iron oxide blade was left. Most of the stuff dug up, when in the ground still, would be a bronze handle with a blade made up of rust colored earth with no solid iron left.

Jim- On the topic of history of the old tools you asked about, here's what I have so far (from a fellow blacksmith who is just starting to write a book:
"I just started my research on a book on the history of Blacksmithing. I have some information but take it with a grain of salt. It is just from the beginning of the search. Bronze rasps have been found in Egyptian tombs from about 1200BC. Iron rasps in Mesopotamia for around 700 BC. Hardened metal files date back to the Middle Ages around the 12th century AD. There is a hacksaw in the Viking Mastermyr tool chest found in Sweden. That chest is generally believed to date to the late Viking/early medieval period ( around 1000 AD). As to the leg vice, I do not have much detail yet. However, there is a clear depiction of them in Denis Diderot's Encyclopedie published in France between 1750-1770." If I do get any more info, I will start a new topic. Pete Stanaitis -------------- |

My oldest useful books are by Theophilus (~1100), Biringuccio and Agricola (1500's). http://www.tms.org/pubs/Books/PDFs/0.../09-1002-0.pdf "The period from the disintegration of Rome to the sixteenth century is , singularly lacking in specific metallurgical information, for there was little connection between the worlds of those who wrote and those who worked in metals." Ancient authors Vitruvius and Heron of Alexandria presented the sophisticated results they could achieve but not the tools or methods. -jsw |

My initial dislike of it came from reworking and patching the brittle plastic with epoxy, until they got an ABS machine that could make durable structural components including hinges. The plastic ink for the mid-80's Howtek ink jet printer that triggered 3-D was quite brittle when printed, though strong when injection-molded. In addition to precisely placing dots of ink we could put a jet in continuous squirtgun mode with a Purge cycle.

It's a good book, but it covers metal as an industry rather than a skilled trade. Biringuccio and Theophilus describe one-man operations better. None of them cover blacksmithing very well. These describe their books. You may be able to download free copies. I can't reasonably confirm them with dialup.
